ATF of yesteryear was sometimes used as an additive (before additives were *cool*)...but they have changed significantly and are thought to actually reduce the lubrication in fuel. And to top it off, the modern diesel engines are not the same beast in production and anything like that through a HPCR could literally wear it out in a few tank fulls.

According to the U.S. Army's quarterly fuel and lubricant bulletin (March 1994), laboratory testing using the Ball-on-cylinder lubricity evaluation (BOCLE) had shown that the addition of ATF to a low sulfur fuel does not improve the fuel's lubricity rating. Moreover, the presence of ATF in fuel can adversely affect other performance properties of diesel fuel.

It a broken record.this mtyh that atf is good is amazing.

yea, back in the 50's some found it to be a cheep detergent so they thought it was good.it is not.

I burn WATF by the gallons, mixed with diesel, jet fuel, and zero issues except coking up the injectors. I am running modified injectors and they are doing much better. 7500 KM's and not as badly coked as the stockers. If I can go 15K before cleaning then i'll be happy.

So there are issues with burning ATF.

What's happening in the combustion chamber and how is it affection the engine oil?

Most likely he is getting the jet fuel free and mixing it with diesel. A better alternative would be to mix the jet, diesel, and quality fuel additive run thru a filter after mixing to avoid engine/injector problems. The only time I would run ATF is if my fuel system was frozen and I would fill the filters with straight ATF in the past to thaw the system out....now a day's specialty products are available for this.

If it is a diesel engine up to the 1980s which include the GM's 6.2L Diesel, then using ATF or WATF may be fine with the IP.

After that, then it is questionable.

I own a GM's 6.5L TD which I would not put any ATF or WATF.I used 2-cycle oil to increase lubricity. The Optical Sensor inside the IP does not like anything colorful especially if it is black.

If the diesel engine is newer than that like Duramax, I would not do it. You are at the risk of ruining engine in a $50K (USD) truck with the injector cost of at least $200 (USD) a piece so at least $2400 just for injector. I heard that is low ball pricing.

Its one of those talks after a few beers that leads you to say..if it was the end of the world what would you drive? That would lead to me saying that i would have a diesel because of all the things that you can pour in the tank and it will get me past the zombies lol. Here is a list of what you can run in your diesel while your neighbors hunt for gasoline.

Yes, minor issues. The money saved over replacing injectors and a few GP's far outweighs the slight inconvience. I am saving $5-$600 a month in fuel costs, I rebuild my own injectors, nozzles cost $150.

Engine oil seems ok, I change it at 7500 km's using Rotella T6 or Lucas 15w40 synthetic. I've put aprox 20K on using alt fuels, looked inside the precup and a slight build up. The motor is coming out in the next 3-4 months as the main webs are cracked and I have a GEP engine to go in.
